ibase_execute

(PHP 3>= 3.0.6, PHP 4 )

ibase_execute -- Execute a previously prepared query

Description

resource ibase_execute ( resource query [, int bind_args])

Execute a query prepared by ibase_prepare(). If the query raises an error, returns FALSE. If it is successful and there is a (possibly empty) result set (such as with a SELECT query), returns a result identifier. If the query was successful and there were no results, returns TRUE.

This is a lot more effective than using ibase_query() if you are repeating a same kind of query several times with only some parameters changing.

例子 1. ibase_execute() example

<?php
   
    $dbh
= ibase_connect($host, $username, $password);

    
$updates = array(
        
1 => 'Eric',
        
5 => 'Filip',
        
7 => 'Larry'
    
);

    
$query = ibase_prepare($dbh, "UPDATE FOO SET BAR = ? WHERE BAZ = ?");

    while (list(
$baz, $bar) = each($updates)) {
        
ibase_execute($query, $bar, $baz);
    }
?>

注: In PHP 5.0.0 and up, this function returns the number of rows affected by the query (if > 0 and applicable to the statement type). A query that succeeded, but did not affect any rows (e.g. an UPDATE of a non-existent record) will return TRUE.
